ground in benghazi? >> they have not. in fact, it was taking so long to get permission to get into tripoli, the fbi deployed closer. they have conducted interviews of those in labia at the time of the attack, but not been able to get -- they've gotten as far as tripoli, but never gotten to benghazi. they made a request that the crime scene be security. as we know from arwa damon's reporting and other public reporting, the state department, we don't know whether the state department put that request to the libyans and whether it was denied. what we know for sure is the crime scene was never secured. the senior law enforcement official i spoke to said, if we get there now, it's not clear it will be of any use to us. the third and really critical and astonishing point to me that they made was, look, one of the things we have to do is question the individuals the libyans have in custody to get to the bottom of this, to understand what they're learning. in fact, they made request through the state department.
